A barometric transmitter characterized by outstanding accuracy and stability provided by a temperature-compensated piezoelectric pressure sensor.
● Barometric transmitter using a high-precision piezoelectric pressure sensor with temperature compensation ● Extremely high accuracy and long-term stability, low hysteresis, excellent reproducibility of temperature characteristics ● Measures atmospheric pressure in the range of 500 to 1200 hPa for analog output and 0 to 1350 hPa for digital output ● Achieves outstanding performance by adopting a silicon-type piezoelectric pressure sensor that integrates both temperature-sensitive elements ● The pressure and temperature measured by the sensor are processed into output signals that are corrected across a very wide operating temperature range of -40 to +85°C by a microcontroller ● Factory calibrated at multiple temperature points within the operating temperature range before shipment ● Suitable for remote data acquisition, such as solar-powered automatic weather stations, due to low power consumption design ● Waterproof housing with protection grade IP67 ▲ Rich output options: Analog current/voltage output, RS232C/RS422/RS485/SDI-12 digital output ▲ Wide operating temperature range of -40 to +85°C, accuracy ±0.1 hPa ▲ Standard protocols: Modbus-RTU, NMEA0183, SDI-12
